The following steps demonstrate how to create a page that is based on the Customers table. When you open the page or click the New Filter button, the script prompts you for a list of countries. The script then limits the number of records that are returned based on the countries that you entered. You can return all records by leaving the list empty.

CAUTION: If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database.

Open the sample database Northwind.mdb.

Create a new page in Design view.

If the field list is not displayed, on the View menu, click Field List.

From the Customers table, drag the CustomerID, the CompanyName, the City, the Region, and the Country fields to the page.

Add a command button to the page, and then set the following properties:

ID: cmdFilter
Inner Text: New Filter

On the Tools menu, point to Macro, and then click Microsoft Script Editor.

On the Edit menu, point to Insert Script Block, and then click Client. This will insert script tags as follows:

<script language=vbscript>
<!--
-->
</script>

Type or paste the following function within the script tags:

Function SetServerFilter()
Dim strFilter, myFilter
strPrmt = "What country do you want to filter by?" & vbCrLf & _
"Separate the list of countries by a semicolon (;)." & _
vbCrLf & "To return all records, leave the box empty."
'Prompt the user for list of countries that are to be returned.
strFilter = InputBox(strPrmt)
If strFilter = "" Then
'Clear the filter criteria when nothing is typed in the input box.
'All records are returned in this case.
myFilter = ""
Else
'Loop through the user's list until there is only one country left.
Do Until InStr(strFilter, ";") = 0
'Add the first country from the list to the filter criteria.
myFilter = myFilter & "[Country] = " & Chr(39) & _
Left(strFilter, InStr(strFilter, ";") - 1) & _
Chr(39) & " OR "
'Remove the first country from the list.
strFilter = Right(strFilter, Len(strFilter) - InStr(strFilter, ";"))
Loop
'Add the final country from the user's list to the filter criteria.
myFilter = myFilter & "[Country] = " & Chr(39) & strFilter & Chr(39)
End If
'Set the server filter.
MSODSC.RecordsetDefs.Item(0).ServerFilter = myFilter
End Function

In the Object list, click cmdFilter, and in the Event list, click onclick. This will insert script tags as follows:
